BOTTLE-NE CK CHE CK-VALVE Specification of Letters Patent. Patented March 24, 1908.

Application filed November 15, 1907. Serial No. 402,238.

T 0 all whom it may concern:

Be it known that I, MARK J. BROWN, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement inBottle-Neck Check-Valves, of which the following is a specification.

My invention relates to devices for practically preventing the refillingof bottles for containing liquors or other fluids, and has for its purpose the providing of a simple mechanism that will be effective for the purpose specified and yet require the least possible modification of form in the bottle neck itself.

In the accompanying drawing, forming a part of this specification, Figure 1 is a vertical sectional view of a bottle neck containing an embodiment of my invention; Fig. 2 is a side elevation of the cap-member shown in section in Fig. 1; Fig. 3 is a side elevation of the valve seat member shown in section in Fig. 1, and Fig. 4 is a further sectional view of the conical weighted valve of the device, said valve and its weight are shown in dotted lines in Fig. 3 in the posi tion they take when the bottle is inverted.

Like reference numerals indicate like parts in all the figures.

10 is the neck of the bottle interiorly provided with the notch-formed recess 11.

12 is the valve seat of sub-conical form having its upper end peripherally slitted at 13 so that the said member may be pressed through the neck of the bottle, and its upper rim sprung outward into engagement with the aforesaid notch 11, the said valve seat being thereby so retained in the bottle neck that it may not be withdrawn without mutilation. The conical cup-formed valve 14 provided with loosely pendent weight 15, suspended on the link 16, is adapted to be closely seated in the base of the conical upper portion of the valve seat member when the bottle is in an upright position. When the bottle is tipped or inverted the said weighted valve falls forward, unseating itself, and permits the free flow of the fluid contained in the bottle. The weight linked to the said valve is prevented from falling too far forward by the annular base 22 of the valve seat member. To prevent tampering with the valve device the thimble formed perforated cap 17 is secured above the valve seat member and in the same recess 11, the rimmed base of said thimble-formed cap being engaged by the upper wall of said recess, which wall is perpendicular to the inner face of the bottle neck. To permit the said cap to be pressed into the bottle neck and sprung into the aforesaid retaining recess, the basal part of said. cap, and its rim 18 are peripherally slitted at 19, so that said cap may be pressed into the bottle neck until the said rim springs outward into the recess, but after engagement with said recess withdrawal of the member without mutilation thereof is effectually prevented. The perforations 20, in the nearly cylindrical wall of said cap, permit the flow of the liquid released by the valve device when the bottle is tipped or inverted. The top of the said tllilliblG-IOIlIlGtl cap is imperforate, to prcvent the insertion of wires for the purpose of tampering with the valve. The whole mechanism is inserted as far as possible below the top of the bottle neck, to further increase the diiliculty of tampering with it, and the cork 21 is inserted above the top of the thimble-formed cap when the bottle is originally filled,*the whole mechanism being driven into the bottle after such original filling and just prior to the corking or sealing of the original package.

My invention is herein above described as embodied in a particular form of construction, but I do not limit it thereto, or to less than all the possible forms in which said invention as hereinafter claimed may be embodied and distinguished from prior devices for like purpose.

1. In combination, a bottle-neck having a retaining recess within its base, a valve-seat member retained in said recess, a cupformed weighted valve normally seated in said valve seat member, and a perforate protective cap above the aforesaid valve device and likewise retained in said recess, substantially as specified.

2. In combination, a bottle neck having a retaining recess within its base, a valve-seat member retained in said recess, a cupformed weighted valve normally seated in said valve seat member, and a laterally perforate protective cap above the aforesaid valve device and likewise retained in said recess, substantially as specified.

3. In combination, a bottle neck having a retaining recess within its base, a valve-seat member retained in said recess, the top of said valve-seat member being peripherally slitted, a cup-formed weighted valve nor- Weighted valve normally seated in said valve seat member, and a perforate protective cap above the aforesaid valve device and likewise retained in said recess, the base of said cap being rimmed and peripherally slitted, substantially as specified.

5. In combination, a bottle-neck having a retaining recess within its base, a valve-seat member retained in said recess, a cup-formed weighted Valve normally seated in said valve seat member, said weight being loosely pendent from the base of said valve, and a perforate protective cap above the aforesaid valve device and likewise retained in said recess, substantially as specified.

6. In combination, a bottle-neck having a retaining recess within its base, a valve seat member retained in said recess, a cup-formed weighted valve normally seated in said valve seat member, said weight being loosely pendent from the base of said. valve, a basal extension of said valve seat member to engage said weight when the valve is unseated, and

a perforate protective cap above the aforesaid valve device and likewise retained in said recess, substantially as specified.

7. In combination, a bottle-neck having a retaining recess within its base, a valve-seat member retained in said recess, the top of said valve-seat member being peripherally slitted, a cup formed weighted valve normally seated in said valve seat member, said weight being loosely pendent from the base of said valve, a basal extension of said valve seat member to engage said weight when the retaining recess within its base, a valveseat member retained. in said recess, a weighted valve normally seated in said valve seat member, and a laterally perforate protective cap above the aforesaid valve device and likewise retained in said recess, substantially as specified.

10. In combination, a bottle neck having a retaining recess within its base, a valve-seat, a cup-formed weighted valve normally seated in said valve seat, and a perforate protective cap above the aforesaid valve device and retained in said recess, substantially as specified.

11. In combination, a bottle neck having a retaining recess within its base, a valve-seat, a weighted valve normally seated valve seat, and a perforate protective cap above the aforesaid valve device and retained in said. recess, substantially as speci fied.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
